PURPOSE:To make the printing end times of all printing presses coincident with each other, by providing an arithmetic part calculating the designated number of printing for every printing press from the total number of printing and a drive part controlling a printing speed. CONSTITUTION:A controller is provided with a total printing number set part 4, a first printing press control part 1, a second printing press control part 2, and a third printing press control part 3. With the start of the operation of printing presses 5-7, the numbers of printing As, Bs, Cs which should be printed until the printing presses 5-7 start decelerating are calculated from the numbers of printing per unit time Ai, Bi, Ci outputted from the printing presses 5-7 and the total number of printing Pt, and the printing presses 5-7 are made to start decelerating when the total numbers of printing Ap, Bp, Cp which were printed by the printing presses 5-7 respectively became more than the numbers of printing As, Bs, Cs. Therefore, even with the dispersion in printing speed or with the difference in printing capacity among the printing presses, in all the printing presses the printing end times can be made coincident and the specified number of printing can be efficiently conducted within a specified time. |
